But the National Party leader said she instead simply delivered a "rah-rah speech" that failed to live up to the hype.

"They think that a photo op 10 months in is a substitute for a plan and an ability to improve the lives of New Zealanders. It's not," he said.

During the speech, Ms Ardern announced "12 priorities" that would drive the Government's working programme, including to "govern responsibly" and "value who we are as a country".

"Every New Zealander can clearly see what the Government is doing and what our priorities are. While not everything we will do is listed, it provides certainty on our direction and the issues we are focused on," she said.

Mr Bridges said the speech was a desperate plea by the Prime Minister to show a united Government after weeks of questions around cracks showing in the coalition.

"This was a lost opportunity for Ms Ardern to admit her mistakes, acknowledge the cracks in her coalition and focus on policies that will genuinely benefit New Zealand," he said. "Instead, we've been given a show designed to distract from her weak leadership and lack of new ideas".

He went on to compare the speech to a TED Talk which "shows a Trump-like attempt to avoid tough questions with a stage-managed pep rally and carefully vetted questions".

ACT leader David Seymour called the speech "underwhelming", but says it was no different to how the previous National Party operated.

"In a speech reminiscent of an 'all style, no new substance' TEDx talk, Prime Minister Jacinda Ardern spouted the same tax and spend policy approach we came to expect from National," he said.

"John Key could have delivered this speech but with better dad jokes."
